This exhaust gas temperature monitor refined by Elektrotechnik Schabus is very specially designed for use with the KDS cable exhaust air controls. The KDS systems distinguish a deliberately opened contact from a cable break by means of a parallel-connected resistor of around 10 kOhm. Window contact and flue gas temperature monitor are connected in series. The negative state (window closed, stove burning) is produced in each case by the closed contact, the positive state (window open or stove cold) causes the control line to become highly resistive. Therefore, a window does not always have to be opened to operate the extractor bonnet, even though the oven may only be in operation very rarely. The pre-assembled 2 metre long temperature-resistant silicone cable can be extended with any 2-core cable if the heat range was reliably left during installation.
Possible applications
- Monitoring tasks to switch off the exhaust air system in rooms with open or closed fireplaces to prevent exhaust gases from being sucked back into the rooms when the fireplace is burning.
- Other monitoring and control tasks, such as controlling the storage tank charging pump in conjunction with KDS units.
Features
- Approved for use in heat-generating systems, TÜV tested according to DIN EN 14597_2012-09
- Intrinsically safe design, maintenance-free with simple mounting on the flue pipe
- N/O contact with pre-mounted 10k cable breakage protection resistor, especially for KDS 110 and 116
- Permissible medium temperature 500°C, on cable and switch head max. 180°C

Involve your chimney sweep in your planning before ordering so that nothing stands in the way of acceptance afterwards. There are significant regional differences over which Elektrotechnik Schabus has no influence.
